Between 1945 and 1951, the city's population grew from 280,000 to 840,000. It decreased from 3,513,777 in 2015 to 3,266,598 in 2024. This decline, which accelerated in the 1990s, is attributed to South Korea's economic shift towards high-tech industries, concentrated around Seoul, and away from Busan's traditional manufacturing base.<ref>{{Cite web |script-title=ko:부산경제통계포털 |url=http://www.becos.kr/statistics/stats03.asp?cate=stats&idx=8&stats=02 |access-date=2025-02-12 |website=www.becos.kr |language=ko}}</ref>
